If you connect as GUEST to your Pocket PC and you are
using ActiveSync 3.x, you may need to re-register the Microsoft XML DLLs.
To register the DLL, issue the command "\WINDOWS\SYSTEM32\REGSVR32
MSXML3.DLL" or "\WINNT\SYSTEM32\REGSVR32 MSXML.DLL" and
"\WINDOWS\SYSTEM32\REGSVR32 MSXML3.DLL" or "\WINNT\SYSTEM32\REGSVR32
MSXML.DLL" Do not type the quotes with the command. This
re-registers the DLL with Windows. Then reboot your PC before trying
to synchronize again.
If you connect as GUEST, then click the start button
and select the “run” option and type “syncmgr /quit”. Then turn off your
Pocket PC and turn it on again.
If you are connecting as GUEST, try reinstalling
Internet Explorer 6 (except XP users). This has fixed the GUEST
synchronization problem for other users. For Windows XP users you
can repair Internet Explorer by following

Synchrologic mail syncing program is installed on their Pocket PC with
less than 64MB of ram. Contact Synchrologic for an update.
If you are using a firewall and you do not allow Port
990 to be used by ActiveSync you will connect as a Guest. For a
comprehensive list of ports that ActiveSync uses please read the
Check and see of the registration key at
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows CE Services and see whether
a key named GuestOnly has a value of 1. If it does then change the
value to 0 to allow you to setup a partnership. An alternative is to
use a free application called ActiveSync Keys which is available at
ActiveSync Keys. NOTE: Microsoft does not support end users
editing the registry so there is no support for performing this.
If you have McAfee Virusscan Enterprise version 7.1.0
installed before you install ActiveSync, you will be able to sync only
once as a guest. To resolve this problem, uninstall McAfee, install
ActiveSync and then reinstall McAfee.
If you have an existing partnership that used to work
when you connected via ActiveSync to your PC, you will need to delete
the existing partnership. Open ActiveSync and click on File -
Delete Partnership to select the partnership and delete it.
If you have an existing partnership on your device this
can cause you to connect as a Guest. Try launching ActiveSync on
the device and deleting the partnerships, If ActiveSync on your
device does not have an option to delete the partnerships, then you will
have to perform a hard reset. Make sure you have a backup of your
data on a flash card or via the Guest connection or you will lose your
data due to the hard reset
